Disgusted and angry....

Kessel if you look through the pics there are two pictures of the prints, size is probably palm of my hand

Sorry for your loss I've been there so know how your feeling...most likely culprit is 1 or more dogs

They are not behind a fence. We’ve never seen dogs around but have seen coyotes. Prints are too large for coyotes but dogs make sense because of how many were killed... whatever it is it’s not getting away next time.

Chickens are on the very bottom of the food chain. Free ranging without a fence is like hanging up a "Free Chicken Dinner Sign".
Sorry about your loss. Most of the folks who lose their flock on here on BYC, have let their defenseless birds roam with no security measures.
I see it once or twice a week. Same thing. If you replace them, I suggest a confinement perimeter if you are unable to fence your entire property. And a hot wire set up.
Again, sorry about your loss.

Looks like dogs to me.They leave behind that kind of mess. So sorry.

if you live on a big pond could be a gator if not could be a black bear or coyote if not fox lastly it could simply be a group of dog or dogs. Soo sorry by the way

This has always been my worst nightmare every time I leave home for errands. All my birds roam throughout my yard during the day. And sleep in there pens at night. I would be devastated coming to to what you came home to. I’m so sorry.

I am so sorry.

It’s so upsetting to see all my time, money, effort be all for nothing. These young ones were such nice ones too... Rhode Island reds and speckled Sussex and a few Sebrights ... never had an issue for 3 years and now this.... not going to rest tonight Incase it comes back

I can't tell what prints you are talking about, is it the tiny one to the right of your hand or is it the one by your fingers. Sorry, I thought you said they were behind a fence. It is not a mink if they were not caged, a mink has a lot of energy but not enough to chase down 30 birds. The bigger track looks like a canine's track.
